Polygon Cozmic CX3.0 MTB - Mixed Shimano Groupset

Ever since I got the Polygon Cozmic CX3.0 MTB 2 years ago, I have upgraded quite a few of the components on the bike. I did not write about them as they are mostly minor changes, with only one component upgraded at a time.

With the latest crankset upgrade, I decided to summarise all the upgrades done so far and list them down. Some of them has significant performance improvements, while others are merely cosmetic or with no major improvements.

All these components are able to work well together as they are all 10 speed Dynasys systems, which means that they all share the same specifications with regards to function.

Final picture showing the entire bike. Weighs 12.5 kg without any accessories.

At 12.5 kg without any accessories, this hardtail MTB can be considered a little heavy. This is mainly contributed by the frame, wheelset and tires which are on the heavy side. The saddle, seatpost, and stem are also stock, which are of course not that lightweight. With an aggressive weight loss program, it seems possible to cut another 1 kg, but that would cost a lot.
